The free quon gas suffers Gibbs' paradox [PDF]

Physical Review D, 1993
We consider the Statistical Mechanics of systems of particles satisfying the $q$-commutation relations recently proposed by Greenberg and others. We show that although the commutation relations approach Bose (resp.\ Fermi) relations for $q\to1$ (resp.\ $q\to-1$), the partition functions of free gases are independent of $q$ in the range ...

Research on the Occurrence State of Methane Molecules in Postmature Marine shales—A Case Analysis of the Lower Silurian Longmaxi Formation Shales of the Upper Yangtze Region in Southern China

Frontiers in Earth Science, 2022
The Yangtze region in southern China is endowed with abundant marine shale gas. Methane molecules exist in either adsorption state or free state in postmature marine shales, depending on the components of shales.

A Flat‐Lying Transitional Free Gas to Gas Hydrate System in a Sand Layer in the Qiongdongnan Basin of the South China Sea

Geophysical Research Letters, 2023
Most marine gas hydrate systems follow a vertical pattern with hydrate overlying free gas. Here we document the discovery of a gas to hydrate system in a horizontal sand layer in the Qiongdongnan Basin of the South China Sea.

Identification of Gas Accumulation Adjacent to the Gas Hydrate Bearing Zone by Inversion Utilizing AVO Attribute [PDF]

Journal of Petroleum Science and Technology, 2018
The presence of gas hydrate and associated gas in the Makran Accretionary Prism, offshore Iran, has been confirmed by various seismic indicators, including the bottom-simulating reflector (BSR), amplitude blanking, and bright spot. The pre-stack analysis

Prediction of Gas Hydrate Formation at Blake Ridge Using Machine Learning and Probabilistic Reservoir Simulation

Geochemistry, Geophysics, Geosystems, 2021
Methane hydrates are solid structures containing methane inside of a water lattice that form under low temperature and relatively high pressure. Appropriate hydrate‐forming conditions exist along continental shelves or are associated with permafrost ...

Shale gas content evaluation for deep strata and its variation: a case study of Weirong, Yongchuan gas fields in Sichuan Basin

Shiyou shiyan dizhi, 2022
The exploration and development of shale gas in China are recently focusing on the deep layers. However, the occurring characteristics of shale gas under high temperature and high pressure are not clear, which imposes great restrictions to deep shale gas

An unusual cause of acute abdomen—Gas-forming liver abscess due to Salmonella enteritidis

Asian Journal of Surgery, 2017
Gas-forming pyogenic liver abscess (GFPLA) is considered to be a very severe form of PLA and carries a high mortality. Klebsiella pneumoniae is the most common pathogen responsible for the disease, whereas cases where Salmonella is cited as the cause are
